Web“Concentrated” hydrochloric acid is an aqueous solution of 37.2% HCl that is commonly used as a laboratory reagent. The density of this solution is 1.19 g/mL. What mass of HCl is contained in 0.500 L of this solution? Solution. The HCl concentration is near 40%, so a 100-g portion of this solution would contain about 40 g of HCl.

Conversely, the halogens follow the opposite order of oxidizing strength: Thus pale green Cl 2 oxidizes Br − to red Br 2 and I − to violet I 2. These colors are better observed if the halogens are extracted into a small amount of hexane.
